Abstract
An experimental system and a method for simulating a gear transmission of an electric multiple unit under wheel-rail excitation are provided. The experimental system includes a gear transmission experimental table and an excitation device. Under the action of the excitation device, the electric multiple unit gear transmission experimental table carries out no-load and load experiments of a gear transmission system to simulate the dynamic characteristic change of the gear transmission system under the wheel-rail excitation environment. The basic experiments of the gear transmission system of the electric multiple unit can be carried out, the wheel-rail excitation received by the gear transmission system during operation of the electric multiple unit can also be simulated, thus making up the vacancy of the experimental researches in the field of electric multiple unit transmission considering the environmental conditions of wheel-rail excitation in China.
